To all whom it may concern:

Be it known that I, FRANCIS W. HARKINs, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented a new Fabrlc- Clasp, of which the following is a specification.

My invention relates to improvements in fastening devices by whicharticles are fastened together, such as a sleeve, hose or othersupporter more particularly, and the ob ect of my invention is toprovide means of quickly and securely accomplishing this result. Iattain this result by the invention illustrated in the accompanyingdrawing in which Figure 1 shows the device, made of sheet metal forheavy fabrics, as closed, the ball for greater clearness being shown asunused. Fig. 2 represents the device as open and as made of wireflattened out sufliciently in parts for use with light fabrics. In Figs.1, 2, the device is shown attached to ends of the connecting band orwebbing. Fig. 3 is a view of one of the arms in Fig. 1 showing The twoarms A and B of the device (Figs. 3, f) have their ends d, n, OZ Nshaped into hooks, both hooks of each arm turned in the same direction,so that when assembled and associated to ether in the device, (Figs. 1,2) these hooks ace each other in pairs, hook cl facing hook cl and hooka facing hook N. Interference of these hooks is prevented by one armbeing placed upon the other. Hook n may be provided with a stud R thatworks in a slot 1" of hook N and serves to hold hooks n and N in place.Stud R also acts as a pivot around which the arms rock when hooks d, dare opened or parted widely. Arms A and B are bowed at bows S S tosecure their proper working. When con structed of sheet material,especially, they are also provided with enlarged bellies O, O to allowthe greater elongation of the slot on of arm A, necessary when heavymaterials are to be connected. Arm A is provided with the slot on forthe reception of stud b of ar m B it also has the stud R which works inthe slot 0 of arm B. But this slot 1" of arm 13 and stud R of arm A maybe disa portion of the attached spring. Fig. 1 is pensed with in case anear 6 is turned over a View of the other arm in Fig. 1 showing on hook Nof arm B to form a housing for the rest of the spring. Fig. 5 is a planof hook at of arm A, as shown in Figs. 1a, 15, the guard for the closeddevice. Fig. 6 is or both may be usedas shown in Fig. 1. Or, a frontview of the guard. Fig. 7 is an elelnstead of the houslng or ear 6 ofFig. 1, a

sleeve 0 Fig. 2 may be used to the same purpose, namely, to keep thehooks n, N together and to prevent interference of the webbing M withtheir action. Sleeve 6 and stud It, working in slot 0" may both be usedtogether as shown in Fig. 2.

In the device the two arms A and B are associated together by means ofthe stud b of arm B made to work loosely in the slot a of arm A, stud 6being provided with an enlarged head to prevent the disassociation ofthe arms. The slot a is slightly curved to lessen friction and allow thefree movement of the movable pivot b which, on the hooks (Z, cl openingto their widest extent, must move over the arc of a circle. In Fig. 1this slot a is shown somewhat elongated to secure more movement of thestud or moving pivot 7), this movement being especially required by thegreater opening necessary to admit the thicker material to be connected,a construction allowed by the clasp being made of sheet material insteadof wire as in Fig. 2. The arms A and 13 Figs. 1, 14: are also connectedtogether by the spring E,

vation of the stud used to pin or pivot the arms together. Fig. 8 is asection of a portion of Fig. 1 made on the plane :0 y. Fig. 9 is asection of a portion of Fig. 2 made on the plane 9 2. On the secondsheet of drawings, Fig. 10 is an edge view of the device shown in Fig.1, in the direction of the arrow, omitting ball and webbing. Fig. 11 isan edge view of the device shown in Fig. 2, in the direction of thearrow omitting ball, webbing and spring. Fig. 12 is a transverse sectionon line to o of Fig. 10, while Fig. 13 is a transverse section on line gt of Flg. 11. Fig. 1A is a modified rear view of the clasp as seen inFig. 1, omitting the webbing and the stud It connecting the large hooks.Fig. 15 is a modified perspective view of the clasp as shown in Fig. 11,

necting the large hooks and shown closed. Fig. 16 is the device shown inFig. 1 except that the ball K is shown in position in use to hold thematerial K.

3. A device for the connection of articles having arms A and B placedone above the other pivoted by a movable pin b, which is at right anglesto the arms A and B and connected together by spring E, arm A being madewith a transverse curved slot a to allow a free movement of the pivot bwhen moving over the arc of a circle on the action of the arms, arm Abeing made with hooks (Z and a, both turned in the same direction, arm Bbeing made with hooks cl, N both turned in the same direction, all partsbeing formed and associated so that on hooks N and 'n being forcedtoward each other, the hooks d, d usually held together by the force ofthe spring E are separate for the reception of a part of the articles tobe connected, substantially as described, for the purpose specified.
